Take derivitive
note
the derivitive of sec(x)=sec(x)tan(x)
so
remember the quotient rule
the derivitive of

so
the derivitive of
so now evaluate when t=pi
we get
sec(pi)=-1
tan(pi)=0
we get

slope=1/pi
use slope point form
for
slope=m and point is (x1,y1)
equation is
y-y1=m(x-x1)
slope is 1/pi
point is (pi,1/pi)
y-1/π=1/π(x-π)
times both sides by π
πy-1=x-π
πy=x-π+1
y=(1/π)x-1+(1/π)
or, alternately
-(1/π)x+y=(1/π)-1
x-πy=π-1
Answer:
Its B
Step-by-step explanation:
1^3 is 1
The volume of a rectangular prism is equivalent to the equation Bh. But to find the base you must first do lw or in this equation 6.1 times 5.4. That equals to 32.94. You then use the height, or in this case 8 and multiply it times 32.94. Your final answer should be 263.52 cm. cubed.
Step-by-step explanation:
divide 63 from 9
=the answer is 7
B = 16
explanation:
b-10 > 5
16-10 > 5
6 > 5
The other answer choices are less than or equal to 5
